Title: Improvements in gauging devices
IPC: G01B5/20
Filed: 1945-03-29
Abstract: 602,740. Gauging screw-threads. STEVENS, A. H. (Sheffield Corporation). March 29, 1945, No. 7988. [Class 106 (ii)] A screw-thread gauge comprises a base having a post which carries an adjustable indicator and an anvil on which is adjustably mounted a carrier for a pair of rotatable rolls which co-operate respectively with a pair of rotatable rolls on the anvil, one co-operating pair of rolls each having several thread-engaging ribs and being adapted to gauge the thread pitch and the other co-operating pair of rolls having only a few thread-engaging ribs in order to gauge the thread-diameter irrespective of the thread pitch, one of the latter pair of rolls being yieldingly mounted on the carrier and adapted to operate the indicator. The anvil 17 is removably mounted in the base 11 and carries rolls 27, 29 which may be mounted on eccentrically-adjustable arbors, and a standard for the carrier 22 on which is mounted a roll 28. The upper roll 26 for gauging the thread diameter is carried by a holder 36 which is supported for yielding vertical movement by two pairs of flat springs 38, 39. A stop on the carrier projects into a recess in the holder to restrict relative movement and the holder engages the feeler 14 of the indicator, which feeler projects through a protective cover 45. The rolls 28, 29 for gauging thread pitch act as a " go " gauge and may be replaced by other rolls when a thread of different pitch is to be checked. In another embodiment, Fig. 10, an upper roll 60 for gauging thread pitch is mounted on a yielding holder so that a thread of correct diameter but incorrect pitch when placed between rolls 29 and 60 will operate the feeler 14 of the indicator. The roll 60 may be finely adjusted by a screw 63 and clamped by a set-screw 64. When the thread-measuring means are not required, the anvil 17 may be replaced by a flat anvil. Specification 544,376 is referred to.

Title: Improvements in and relating to the burning of pulverised fuel within the firebox ofsteam locomotives
IPC: F23C99/00
Filed: 1922-03-20
Abstract: 177,179. Buell, R. N. March 20, 1922. Pulverulent-fuel furnaces.-Pulverulent fuel is supplied to the fire-box of a locomotive through burners 2 arranged in the front wall and directed rearwardly. The fuel is conveyed to the burners by a pipe 1 connected to a storage bunker at the rear of the locomotive. Air entering through a funnel-shape inlet at the front of the smoke-box is heated in a coil 9 and led by a pipe 10 to one of the burners for secondary combustion. If it is found that the velocity of the flame causes incomplete combustion and unconsumed fuel enters the smoke tubes, the fire-box may be provided with an additional burner delivering jets of fuel opposed to the fuel jets from the burners 2. The combustible mixture in the fire-box may be supplied with air or superheated steam delivered in opposite direction to the stream of fuel. Slag collecting on the incline 12 is removed by steam jets 14 on to a " drip tile " 11 and dumped into the ash-pit 13.

Title: Apparatus for Facilitating the Packing of the Propeller Shafts of Ships.
Inventor: GAY ALEXANDER
IPC: B63H23/36
Filed: 1917-06-06
Abstract: 116,343. Gay, A., and Rutherford, A. B. June 6, 1917. Packing, inserting.-Mechanism for facilitating the insertion of packing in a stern tube while the vessel is afloat consists of a ring a, Fig. 3, formed in halves which are secured together by plates b, riveted to the end of one half, and secured by studs c to the other half. The ring a is secured to the gland bolts f by nuts, or by hooks g which screw into brackets h secured to the ring a. The brackets h and the plates b project beyond the edge of the ring a so that a gap i is left between the ring a and the stuffing-box flange e<2>. In repacking a box, the gland d is slackened clear of the gap i and keys k are then inserted in the gap to retain the old packing. The gland is then slackened further and fresh packing is inserted in the ring a and is forced into the stuffing-box by the gland, the keys k being removed. Alternatively, the ring a may be bolted to the stuffing- box flange, or formed in one with it, or slots for the insertion of the keys k may be formed in the stuffing-box behind the flange e<2>, or in a sleeve containing the packing and projecting beyond the mouth of the stuffing-box. In the modification shown in Fig. 10, which enables a box to be completely repacked, clips q embracing the gland bolts f are bolted to the ring a, and may be used to hold the ring temporarily by inserting packing- pieces between the ring and the bolts f. In repacking a box, the gland d and the ring a are slackened and the old packing is removed. Keys are then inserted in slots v in the ring a and packing is inserted in the ring. The ring is then pressed up to the stuffing-box flange by the pressure of the gland d on the keys in the slots v and by nuts f' on the bolts f bearing against the clips q. The keys are then removed and the packing is forced into the box by the gland and is retained by inserting the keys in the gap i. Further packing is then inserted in the ring a and is forced into the box by the gland, the operation being repeated until the box is full. The keys t, as shown in plan in Fig. 15, are preferably formed with wings t', which act as stops to prevent the keys from being driven against the shaft, and form guides for wedges u by which the keys are secured.

Title: Process for the Continuous Casting of a Composite Metal Casting
IPC: B22D11/00
Filed: 1967-02-21
Abstract: 1,153,082. Continuous casting-machines. KENNECOTT COPPER CORP. 21 Feb., 1967 [11 March, 1966], No. 8266/67. Heading B3F. In the continuous production of a composite metal casting a tube T is cast between a mould 1 and mandrel 4 and a molten core metal of relatively lower melting point is introduced into the tube T through the mandrel 4 to form a solid core C. The tube T is cooled by water sprays N and withdrawn from the mould 1 by pinch rolls 17. The control of the level 22 of the molten core metal inside the tube T is achieved by a throttle rod 15 in conjuction with a radiation sensing means 23 and the composite casting is further cooled by water sprays N to extract heat from the core metal and solidify it so as to keep alloying interaction between the core and tube materials to a minimum. The mould 1 is made of graphite, is water cooled 2, has tapered walls 3 and may be vibrated. The mandrel 4 may be formed of graphite or cast-iron. In examples the tube T may be iron, copper, nickel or aluminium and the core may be aluminium, sodium, magnesium or lead. In a specific example a copper tube has an aluminium core. The composite casting may be swaged to form rods, drawn into clad wire, punched and rolled into pipe, or rolled flat to form clad sheets or strips.

Abstract: 951,415. Blood oxygenating apparatus. ABBOTT LABORATORIES. March 7, 1961 [March 14, 1960], No. 8364/61. Heading A5R. [Also in Division B1] In blood oxygenating apparatus oxygen is bubbled through a rising column of blood which then passes into a defoaming chamber, where it is contacted with a surface-active defoaming agent, and thence to a filtering chamber, and each transfer from one chamber to the next takes place below the surface of a steadily maintained blood level. In the apparatus described, blood is introduced through a passageway 40 which is surrounded by a porous membrane 27 through which oxygen is supplied under pressure, so as to pass up through the column of blood in the tube 13 in the form of fine bubbles. The oxygenated blood passes out of the upper part 14 of the tube 13 and downwards through defoaming material 17, which comprises polymeric dimethyl siloxane and silicon dioxide, to an outlet duct 25. This leads into a rectangular chamber 11 which is divided into two compartments by a vertical filter screen 44a, so that the blood flows through the screen to the second compartment. Communicating ducts at the rear then lead the blood into a second, similar filter chamber 12 and so to the outlet 38. In each case the communicating passages between adjacent compartments are below the blood level 74, so as to avoid the transference of foam. Excess oxygen and carbon dioxide pass out of the system through orifices 19, 35, 36, all of which are provided with filter plugs.
